The Superfund Remedy Report (SRR), Thirteenth Edition, formerly called the Treatment Technologies for Site Cleanup: Annual Status Report (ASR), was published by the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) in September 2010. The SRR presents the analysis of Superfund remedial actions based on: (1) remedies selected in Records of Decision (ROD) and ROD amendments, and (2) actions modified in Explanation of Significant Differences (ESD), for fiscal years (FY) 2005 - 2008. The SRR also follows trends in remedy selection using ASR data from FY 1982 - 2004 combined with SRR data. The SRR analyzes remedies selected or modified in 594 decision documents, but does not include project-specific updates that were presented in past editions of ASR. In addition, SRR also includes brief project highlights related to green remediation, in situ bioremediation, and high resolution site characterization. The online version includes downloadable appendices with data for several key tables and figures in the report and new appendices that summarize all the remedy components selected for sources and groundwater in each individual decision document.
